New Flyer Industries D40i
|Years of manufacture||1999 to 2007|
The New Flyer Industries D40i, dubbed the Invero, was a low floor transit bus. Introduced in 1999 with the intention of eventually phasing out New Flyer's traditional low floor bus, the first production units were sold in 2002 to St. Catharines Transit and were numbered 90-95. However sales of the Invero never truly gained momentum, with only OC Transpo operating a substantial fleet of the buses. The D40i was taken off the market in early 2007.
The Invero was introduced with a number of innovations, some of which would become common in the industry. Instead of a traditional plywood subfloor that was secured by screws, the Invero used phenolic coated balsa wood that was secured with adhesive. The HVAC was mounted at the front of the bus to improve circulation and weight distribution. The Invero was also one of the earlier buses to use a multiplexed electrical system.
Passengers benefited from a larger glazed surface and lighting that was diffused in a manner to reduce glare on the windows and windshield. The interior layout allowed for a gain of five seats over New Flyer's traditional low floor. The driver's area featured improved ergonomics and simplified control layout. The 18 inch steering wheel had improved grips, and the foot pedals could be adjusted. The area was also designed to stay at a comfortable temperature at all times with direct air conditioning current and heating around the feet.
The Invero platform was never formally built in other lengths or with other drivetrains. Although Stewart & Stevenson integrated the GM-Allison parallel hybrid system into new Invero buses for the Roaring Fork Transportation Authority.
In 2006, a hydrogen fuel cell hybrid powered Invero was presented by Hydrogenics and the Province of Manitoba. Working with New Flyer, Hydrogenics converted a former demonstrator bus—fitting it with three HyPM 65 fuel cell modules. ISE Corporation supplied the hybrid system, which included 170 kW wheel-mounted electric motors from Siemens. Ultra-capacitors from Maxwell Technologies were used to store electricity.
